A detection system for pesticide residues in fruits and vegetables

Abstract

The invention discloses a fruit and vegetable residual pesticide detection system, which includes a computer, a storage server is arranged on one side of the computer, a sub-unit is arranged on one side of the photosensitive measurement module, and an upload unit is arranged on one side of the sub-unit , the lower end of the voice component module is provided with a processing device, the surface of the processing device is provided with an execution panel, the lower end of the detection port is provided with an input interface, the surface of the input interface is provided with a fixture, and one side of the input interface is provided With the transmission nozzle, the beneficial effect is that the fruit and vegetable samples are placed through the transmission nozzle, which has the advantages of low power consumption, stable performance and long transmission distance. Bypassing the detection port and repeating the instructions of the scanning unit, recording unit, and analyzing unit, the secondary detection degree can be increased without damaging the fruits and vegetables. This method has high precision and repeatability, and good sensitivity and linear range.

Description

technical field [0001] The invention relates to the application field of pesticide detection, in particular to a detection system for pesticide residues in fruits and vegetables. Background technique [0002] Pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used are DDT, HCH, etc. They can eliminate pests in large quantities, but they have good stability and can exist in the environment for a long time. The accumulation in animals, plants and human body was eliminated because of this, and then organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides, but their toxicity was too high, which was very harmful to humans and animals; in recent years, a batch of high-efficiency and low-toxicity pesticides However, no matter how advanced pesticides are, they belong to the category of chemicals after all, which will affect the environment and affect the health of the body. Therefore, ...

[0002] Pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used are DDT, HCH, etc. They can eliminate pests in large quantities, but they have good stability and can exist in the environment for a long time. The accumulation in animals, plants and human body was eliminated because of this, and then organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides, but their toxicity was too high, which was very harmful to humans and animals; in recent years, a batch of high-efficiency and low-toxicity pesticides However, no matter how advanced pesticides are, they belong to the category of chemicals after all, which will affect the environment and affect the health of the body. Therefore, in order to Food safety requires the detection of pesticide residues in food. The Chinese patent application number CN201710313525.4 discloses a real-time pesticide detection system and method in the field, including a detection module, a wireless sending device, a wireless receiving device, a storage device and a display. By cooperating with the wireless transmitting device and the sampling of the robotic arm, the purpose of real-time sampling and real-time detection in the field is realized, so that the detection data has no lag, and the accuracy of the instrument analysis detection method is the highest, but the detection process is complicated and the detection performance cannot be guaranteed. , biochemical detection technology has developed rapidly, but the initial investment is large and the experimental conditions are harsh, which cannot meet the requirements of use
